Sugiyama Satoko (杉山 里子) Is a character from Girl Friends. She is friends with Akko and the rest and is especially close to her best friend Tamamin, Sugiyama is the oldest of Akko`s friends and the most flirtatious and erotic. She really enjoys mixers and has much knowledge on dating so she often gives out advice for it she constantly juggles boyfriends and currently has five of them at the same time.
Sugiyama has sandy brown curly long hair and is usually mostly seen wearing her usual school uniform. She is easily the tallest of Akko`s friends and easily towers over everyone.
Sugiyama is the most calm and mature of Akko`s friends and can be quite aloof much of the times, She also has a very flirtatious nature and has much knowledge on dating and has currently five boyfriends at the same time. Due to her great knowledge and maturity many of the characters expect Tamamin often go to her for advice on various things ranging from dating advice to how to take care of sunburn. Despite her nature Sugiyama can be surprisingly observant and has a sharp eye for certain things as she was the only person of Akko`s friends to see that Akko and Mari have feelings and for each other but don`t know how to express them which result in them hurting each other. Due to her sharp eye she is currently the only one who knows Akko and Mari are dating by the end and is left in shock when Tamamin does not notice, Sugiyama can also become angry or annoyed at times mostly when it comes to Tamamin`s antics such as cosplaying at odd times as she does not like otaku`s. Sugiyama also has the tendacy to strip often whenever she gets the chance she will remove some clothing or show people unnecasary things such as when she pulled her skirt up to show where she got tan lines at on purpose or taking her shirt off claiming it was too hot in a photo booth with Akko and the others much to Mari`s shock.
By far her most important relationship is with her close friend Tamamin, Despite her being an otaku the two get along very well and are rarely seen apart from each other Sugiyama also often invites Tamamin to any events she sets up such as mixers or beach trips but does get annoyed when she does things like cosplay at odd times. And despite doing it supposibly for fun Sugiyama shares a very intimate relationship with Tamamin physically, The two often kiss each other especially when drunk and Sugiyama has once said that the two of them have kissed atleast a hundred times already and in one instance Sugiyama even grabs and touches Tamamin`s breasts to put what Tamamin had said to the test. Despite all that the two claim not to have feelings for the other.
Sugiyama has been friends with Akko ever since Akko first entered high school and from there they have been friends often discussing either makeup, clothing and magazines to mixer plannings and such. Akko also looks to Sugiyama for help many times often coming to Sugiyama about problems she has with Mari such as the time Mari kept acting strangely and avoiding her or discussing Mari`s confession and wondering how to handle it or talking to her about her worries of Mari when her confession didn`t quite reach her. Due to Sugiyama`s constant help and support of Akko she was able to finally reach out to Mari and in the end become a couple though Sugiyama`s help was distant and limited as she wanted Akko and Mari to resolve the issue themselves which greatly helped the two of them mature and understand things much clearer.
Though they are not seen directly they are often seen through Sugiyama`s E-mails on her phone, She constantly jumps from boyfriend to boyfriend and can`t make up her mind at which one she ultimately wants to be with. While at first the five of them didn`t know about the other eventually it is revealed her five boyfriends do find out about each other as Sugiyama told each of them and apologized but instead of being upset all five of them are not and continue to date her. As seen at times they seem to spoil her a lot often buying gifts and the like.
It was due to Sugiyama that Kuno met and ended up with Ouji as he was part of the group of people Sugiayam bought to the mixer that Akko and Mari opted out of. Kuno looks to Sugiyama as a big role model and often looks for her on advice on things such as beauty and dating tips. And it was once noted by Kuno that she had wished she was erotic just like Sugiyama when Akko explained about how perfume smells evaporate.
Though the two never interact as much as Kuno does with her Urara and Sugiyama share good relations and Urara seems to look up to Sugiyama too but too a much less extent than Kuno she once asked Sugiyama to teach her about how to take care of Sunburns
Sugiyama and Tamamin are seen briefly flirting with and and asking Harada questions soon after Mari had broken up with him. Not much esle is seen of Sugiyama and him from what it seems like from their brief meeting he is a bit weirded out by her and her actions and has him wondering if they are friends of Mari`s as they had the same uniform as her.
Though the two are not seen interacting much it is revealed that aswell as Akko and Tamamin Sugiyama likes to tease and bully Naru too and has embarrassed her by leaving something in the staff meeting room.
